METHODS FOR UE TO REQUEST GNB TCI STATE SWITCH FOR BLOCKAGE CONDITIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17808923 titled 'METHODS FOR UE TO REQUEST GNB TCI STATE SWITCH FOR BLOCKAGE CONDITIONS

Simplified Explanation

The abstract describes a method and apparatus for a User Equipment (UE) to request a switch in Transmission Configuration Index (TCI) state for blockage conditions. Here is a simplified explanation of the abstract:

  • The apparatus predicts when a blockage condition is likely to occur for a specific beam that is communicating with a network node.
  • It then transmits a beam switch indication to the network node, informing it of a scheduled change in TCI state from the first beam to a second beam in response to the predicted blockage condition.
  • The apparatus may schedule the beam change to the second beam based on the predicted blockage condition.
  • The UE correlates its beam change to the second beam with a corresponding beam change at the network node.

Potential applications of this technology:

  • Wireless communication systems where blockage conditions can occur, such as in urban environments with tall buildings or in indoor environments with obstacles.
  • 5G and future wireless networks that utilize beamforming techniques to improve signal quality and capacity.

Problems solved by this technology:

  • Blockage conditions can significantly degrade the quality of wireless communication signals, leading to dropped calls or slow data speeds.
  • By predicting blockage conditions and proactively switching to a different beam, the system can maintain a more reliable and stable connection.

Benefits of this technology:

  • Improved user experience by reducing the impact of blockage conditions on wireless communication.
  • Increased network efficiency by optimizing beam selection based on predicted blockage conditions.
  • Enhanced reliability and stability of wireless connections in challenging environments.


Original Abstract Submitted

Method and apparatus for a UE to request a TCI state switch for blockage conditions. The apparatus predicts a blockage condition to a first beam communicating with a network node. The apparatus transmits, to the network node, a beam switch indication indicating a scheduled change in a TCI state mapped from the first beam to a second beam in response to the predicted blockage condition. The apparatus may schedule a beam change to the second beam based on the predicted blockage condition. The apparatus may correlate a beam change to the second beam at the UE with a corresponding beam change at the network node.
